- Sorry to break in, but if this is that announcement last year that was
- in the the news (of course it is because it was first time that it had
- ever been used as proof according to all the media sources I read - and
- I read a lot as this subject matter interests me), a follow-up article
- said they had jumped to conclusions too soon, and I think they said,
- after further research, that it may be a binary star instead (although
- this part may be wrong). While the theory of the 'wobble' is very
- valid, it has, as of yet, not been enough to make the conclusion that
- planets are orbiting other star systems. The ONLY system so far known to
- have planets orbiting it is ours.
-
- I believe there are other planettary systems, the chances against it are
- astounding. I just hope to be around (and I probably will) when they
- discover them. Who knows, since I'm going for degrees in the
- astonomical field , I might just locate one? I can only hope! :-).
-
- :There is also a good deal of other (indirect) evidence in the form of
- :spectrographic studies, which may be found in many introductory text-
- :books (at least in summary form). I would direct you to these for
- :further information.
- :
- :One might raise the objection that these companions are too large to be
- :called planets. If they are nonluminous and orbiting a star, I don't
- :know what else you'd call them. In any case, their existence could
- :not possibly hurt the chances of smaller planets being present. I
- :hope this is useful.
